RO PE- SOCKET.

SPECIFICATION forming part of Letters Patent No. 499,954, dated June 20,1893. Application filed January 28, 1893. SerialNo. 45 1 lN mml l-l Toall whom it may concern.-

Be it, known that 1, DAVID W. BLACK, of Butler, in the county of Butlerand State of Pennsylvania, have invented a new and useful Improvement inRope-Sockets, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide an improved rope socket for useas a deep well tool and to avoid the disadvantages incident to formerrope sockets, which have been difficult to apply and often impossible tofree from the rope when it is desired to remove them.

To this end my invention consists in a rope socket having wedge slipsanda removable seat adapted to clamp the wedge slips on the rope, and meansby which the seat is forced positively against the slips so as to pressthem against the rope and cause them to hold the same.

I will now describe my invention so that othersskilled in the art towhich it appertains may manufacture and use the same, reference beinghad to the accompanying drawings, forming part of this-specification, inwhich- Figure 1 is a longitudinal sectional view of my improved ropesocket as applied to the rope. Figs. 2 and 3 are detached views of theslips and removable seat. Fig. 4 is a longitudinal sectional view of amodification, and Figs. 5 and 6 are detached views of parts of the same.

Like symbols of referenceindicatelike parts in each.

In the drawings, 2 represents one of the parts of the socket, having atits lower end the usual threaded portion adapted to be engaged withother tools in the well, and having at its upper portion a tubularopening for the rope and an annular recess 3, having a seat 4,.

in which are seated the wedge-slips 5, which are of segmental conicalform and may be of any suitable number, preferably three. On their innersides they are preferably serrated so that they may hold the ropesecurely, and their upper ends are comically tapered so as to fit in thetapered seat of thefremov'able sleeve 6. This annular sleeve 6 may alsobe made solid or in segments corresponding to the segments of thewedge-slips 5, and it is provided at its lower end with the conically-.tapered seat 7, so that the sleeve may fit over and coincide with thetapered end of the slips 5. The upper part 8 of the socket is tubular"in form, and at its lower end is a screw-thread which fits in thethread in the recess 3 of the lower-portion 2 of the socket, so thatwhen the two parts 2 and S'are screwed together, the end 10 of the part8 will act as a follower and bear down on the sleeve 6.

The operation is as followsz-The rope 9 is passed through the tubularopening in the part 8 and inserted into the end of the part 2. The slips5 are then inserted in the recess 3, on the seat 4, around the rope, andthe sleeve 6 is placed in the recess over the tapered end of the slips.The upper part 8 of the socket is then screwed down in the recess 3until it bears on the sleeve 6, sufficiently to cause the slips to bindon the rope so as to hold the same. When it is desired to detach thesocket,

the part 8 is unscrewed, and on pulling up the rope the sleeve 6 andslips 5 are withdrawn from the recess 3, and being formed in segmentsthey fall apart and from off the rope.

In Figs. 4, 5' and 6 I show a modified construction of the apparatus, inwhich the recess 3-is formed in the lower portion of the upper part 8 ofthe socket, and the follower is formed on the lower part 2 of thesocket, and while thewedge slips 5 are the same in construction as inthe other form of socket, they here occupy an inverted position and arecompressed against the rope by the upward pressure of the sleeve 6 andthe follower 10. On the upper part of the follower 10 is an annularcollar 11, and on the inner face of the sleeve 6 is a correspondingannular groove 12, into which the collar 11 fits when the segmentsformingthe sleeve 6are placed around the follower.

The operation is as follows-The rope is passed through the part 8 andinto the openthe recess 3 around the rope. The segments forming thesleeve 6 are then placed around the follower 10, the collar 11 fittingin thegrooves 12, and the follower is screwed into the recess 3 untilthe sleeve 6 compresses the slips 5, as already described. When it isdemg in the part 2 and the slips 5 are placed in sired to detachth'esocketythc part 2 is imscrewed from the part 8, and as the'follower 10is withdrawn from the recess 3 the sleeve 6 being connected with thefollower is also withdrawn, releasing the slips 5.

The advantages oii my invention will be apparent -to those skilled inthe art. The rope socket is simple in construction, and is not onlyeasily applied, but is also easily removed.

I claim 1. A ropesocket having a tool connection, an opening for therope, Wedge-slips havingin 1 clined outer surfaces, a loose clampingsleeve, having an interior inclined face and a follower; adapted to bearon: the s1eeve,s1'1bstanr 5 tially as described.

2. Arope socket having atool connection, an opening for the rope, wedgeslips, a clamping sleeve, and a follower, the sleeve and follower beingconnected with eachother; substantially as described. I i e In testimonywhereof I have hereunto set my hand.
